The return trip was 21.2 hours long.
Step-by-step explanation:
Given,
Speed of plane from US = 212 mph
Speed of plane on return trip = 232 mph
Let,
x be the time taken on return trip.
Time taken from US = x+2
We know that;
Distance = Speed * Time
Distance of plane from US = 212(x+2) = 212x+424
Distance on return trip = 232x
As the distance will be same, therefore,

Dividing both sides by 20

The return trip was 21.2 hours long.

the probability of an event occurring, it is easy to compute the probability that the event does not occur. If P(A) is the probability of Event A, then 1 - P(A) is the probability that the event does not occur. For the last example, the probability that the total is 6 is 5/36.
Answer:
I think you wanna know exactly it's graph
See f(x)= 2 e^x +3
e^x is exponential function which is always positive and so lies above x axis
Multiply by 2 make it's incrementation in slope and now it will pass through (0,2)
Also adding 3 shifts graph 3 unit above y axis
So Now it will pass through (0, 2+3) that is B) (0,5)
Now At x approaches to minus infinity it will shift 3 unit up from 0 to 3 So it will pass through (-infinity,3)
Now see the pic
Answer:
Example: Suppose you give $100 to a bank which pays you 10% compound interest at the end of every year. After one year you will have $100 + 10% = $110, and after two years you will have $110 + 10% = $121.

Problem:
If you deposit $4500 into an account paying 7% annual interest compounded semi anualy , how much money will be in the account after 9 years?
Result:
The amount is $8358.7 and the interest is $3858.7.
Explanation:
STEP 1: To find amount we use formula:
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
After plugging the given information we have
STEP 2: To find interest we use formula , since 8358.7 P = we have:
3858.7
